How can I prohibit unassigning a ticket in specific status (In Progress)?

Question

I set a validator for transitions to In Progress status that makes "Assignee" field mandatory. So person who moves ticket to In Progress is prompted to assign the ticket.

But I cannot find a way to prohibit unnassigning ticket that is in In Progress status. I need to make this field mandatory for this status only.

Hello,

You should add a workflow property to this status:

jira.permission.assign.denied

You can find more info here:

Add a property to the In Progress status like:

jira.permission.assign.denied
